LEWISTON, Maine (AP) — Activists who succeeded in legalizing possession of marijuana for recreational use in Portland are now turning their attention to three more Maine communities.

David Boyer from the Maine Marijuana Project says activists will be at polling places Tuesday to seek 1,000 signatures in Lewiston and South Portland to force local referendums the issue. They'll also be seeking 100 signatures to put the matter before the Town Council in York.

The proposal is similar to one enacted by Portland voters in November except that the amount of marijuana would be smaller — 1 ounce instead of 2.5 ounces.

Boyer said the smaller amount is in line with voter-approved marijuana laws in Colorado and Washington. It would remain illegal to use marijuana in public or for those under 21 to have it.
